The White-lipped Pit Viper is a very adaptable snake which can be found in wooden and bushy open areas up to 500 meters. It is often found near human settlements. It prefers to stay near to the water. The snake is nocturnal and in search for food (rodents, frogs, lizards, birds) they also move on the ground at night. The Pit Viper strikes quickly and accidents with humans happen frequently. White-lipped Pit Vipers mate in Thailand in September and October. The females give birth up to 16 offspring, which are born in a membrane which the babies break open just after birth. The juveniles have the same coloration as the adults.
